1. A system for monitoring angles of a profile of a bottom of a borehole at stages of reaming during construction of communications using a method of horizontal directional drilling, the system comprising:
a computer with installed software for processing and building a profile of the bottom of the borehole after each reaming and configured to connect a device for monitoring angles of the bottom of the borehole to the computer,
the device for monitoring the angles of the bottom of the borehole comprising a housing, the device for monitoring being spaced apart from and in the borehole behind a reamer during reaming;
the housing comprising accelerometers, an electronic board with a processor, a device for recording and storing information of the angles of the profile of the bottom of the borehole obtained during each stage of reaming, and a power source.
